FUEL SYSTEM
Diesel Fuel
Use No. 2 diesel fuel with a cetane rating of 45 or higher. Never use kerosene or home heating oil since
these fuels do not have the same lubricating properties as No.2 diesel fuel.
In cold weather particularly, water vapor is produced by condensation when air is present in the fuel tank.
Keep fuel tank(s) full and completely free of dirt and water.
Fuel Filters
A primary fuel filter of the water
entrapment type must be installed be-
tween the fuel tank and the engine. A
primary fuel filter, shown here, is
available from your local Westerbeke
representative or your boatbuilder.
This filter, adapted for boatbuilder
use, comes complete with fittings for
either hose or metal tubing. Mount it
in an accessible place, inspect it often
and drain off water accumulation fre-
quently.
If a water trap type filter is not installed
between the fuel tank and the engine-
mounted fuel system, any water in the
fuel system will tend to lay in the bot-
tom of the electric lift pump. Internal
metal parts of the lift pump will rust.
Particles will pass on to filters and
eventually to the injection pump and
injectors with damaging results and
the possibility of expensive repairs.
Remember, water damage to the fuel
system is not covered under the

Westerbeke warranty. The owner/operator is responsible in making sure that fuel reaching the engine's in-
jection equipment is free
of
impurities. This process is accomplished by installing a proper filtration/separa-
tion system and maintaining this system.
In addition, any gasoline in the fuel system will damage the engine's fuel injection pump assembly and in-
jectors, as gasoline does not have the same lubricating qualities as diesel fuel.
Although most boatbuilders supply a water trap/filter, some do not. Westerbeke offers a sedimentary/water
trap/filter as an optional extra at moderate cost. The filter is supplied with fittings for either hose or metal
tubing fuel lines.
